Title: Houses become desaturated when visited

- within button pressed method, set house image to the appropriate grayscale image
- removed unnecessary creation of more navigation controllers within display interior controller and display mini game controller functions
- moved viewDidAppear code to viewDidLoad so stage does not reset each time it appears
- simplified initialize houses into a for loop
